Hi all. I have just bought a Celestron 18771-CGL power tank to allow me to get out to the dark skies of the South Downs with my Nexstar 8SE. This is a great bit of kit because it's so light and portable and powers the scope for hours no problem. However, I've also been thinking about getting a dew heater and the only downside of the power tank is it's lack of a second 12v output. I was looking on the First Light Optics website and they sell a DC splitter cable to allow two devices to be powered from a single output. I'm not an electrician obviously, but logical tells me if the dew heater controller is also a 12v device there should be no problem running both the scope and the heater at the same time other than draining the battery faster. Is anyone using a splitter cable in this way? Or can anyone confirm my logic is flawed?
Ok, apologies if this sounds crazy, so here goes. 1: Counter Balance track on OTA 2: Half kilo counter weight on track adjustable. 3: Power Tank / Jump starter on floor. 4: Trailing Leads causing trip hazard. 5: That all adds up to ££££££'s and extra kit to pack. Ok now my solution, or am I crazy. Aluminium T'Track attached to OTA. T'Track sliding bolt and a bracket. POWERBANK attached as counter weight/Power supply. I can they run cables to stuff mounted on OTA / Microfocuser / imaging Kit / Goto Power Supply etc. So no trip hazards, cables neat tidy on OTA, no cord wrap issue, smooth power supply, counter balance all from one piece of kit. Going to try it maybe or am I crazy. I don't have a lot of extra weight on my LX90gps 8" so about half a kilo should do it. What do you think??????
